dovecot authentication issue
Hi,
I have been trying to get the Dovecot authentication via LDAP to work on my Ubuntu Server 10.04 but with no luck. I have postfix, dovecot, squirrelmail and openLDAP running at the moment on the same server.
My goal is rather than creating new accounts on the server for each of the users (time consuming), I decided to allow a list of users from LDAP to be able to login to the mail server.
The problem I have been having is when a user login to squirrelmail, there are error messages in the mail.log file as follows
Aug 30 17:39:37 server1 dovecot: auth(default): passwd(mike_lee,127.0.0.1): unknown user
Aug 30 17:39:37 server1 dovecot: auth(default): ldap(mike_lee,127.0.0.1): invalid credentials
Aug 30 17:39:44 server1 dovecot: imap-login: Aborted login (auth failed, 1 attempts): user=<mike_lee>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, secured
I do not know why it says unknown user and invalid credentials there. I wonder if anyone might be able to point out where it went wrong.
Here is the details of dovecot-ldap.conf
hosts = localhost

I hope the information above would help you to help me out.
Any help is much appreciated.
Thank you
